APPARATUS FOR STARTING INTERNAL-COMBUSTION MOTOR/S.

To all whom it may concern:

Be it known that we, WALTER CLossoN and JosnrI-I MmssnN, both subjects of the King of Belgium, respectively residing in Verviers and Ensival, Belgium, have invented certain new and useful Improvements in Apparatus for Starting Internal- Combustion Motors; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked therein, which form a part of this specification.

This invention relates to apparatus for starting internal combustion motors of various constructions, and it has for its object to obviate the inconveniences inherent in other systems of starting such as turning a crank, and it insures a certain start without the driver having to leave his place.

Under this invention we provide a carriage or slide that can be caused to traverse a screw of any pitch whatever, in order to stretch or compress and thereafter release and be returned to its starting point by a starting spring of appropriate shape and section. lhe said carriage or slide has attached thereto one end of a cable which passes over a free -wheel, or ratchet, pulley or coiling box secured on the engine shaft, and has the other end thereof secured to a spring drum or the like, the arrangement being such that the rapid return of the carriage under the action of the aforesaid spring causes the cable to rotate the pulley on the engine shaft and thus start the engine.

In order that our invention may be clearly understood we have hereunto appended an explanatory sheet of drawings which show, by way of illustration or example, one form or embodiment of our invention.

Figure 1 is a plan view, showing the contrivance applied to the chassis of a motor car from which the coach body is removed. Fig. 2 is an elevation, to a larger scale, along A, B, of Fig. 1, showing in detail the carriage or slide with clutches. Fig. 3 is an elevation along C, D of Fig. 1 showing the speed reducer and clutch gear for making the connection between the shaft of the motor and the screw of the carriage or slide.

Specification of Letters Patent.

Application filed December 4, 1912.

Patented Dec. 23,1913. Serial No. 734,959.

In carrying our invention into effect or practice the shaft 1 of the motor is connected with an intermediate shaft 2 by means of a worm 3 thereon which engages with a worm wheel 4 keyed on to the said shaft 2. The latter shaft 2 carries a clutch member 7 which can engage with the corresponding clutch member secured on the socket of the worm 6, which worm engages with a helicoidal pinion 8 keyed on to the extremity of a screwed spindle 5. By means of the lever handle 9 attached to the clutch 7 and actuated by a spring 4-5, the worm 6 can be connected. with, or disconnected from the shaft 2. The screwed spindle 5, which may have a left hand or a right hand thread, is carried at one end in a bearing bracket 10, while at the other end it is mounted on a screwed pivot 11, which is screwed through a stirrup 12 fixed to a cross tie 18, and which is intended to regulate the position of the screwed spindle 5. On said screwed spindle 5 is mounted a carriage 15, the central ring or boss 14- of which carries two columns 16 and 16', and, loosely mounted on said columns and supported by shoulders 18 thereon is a wedge or slab 17, having a part provided with parallel edges at each extremity of the wedge shaped part and a slot extending along the center thereof by means of which it is mounted on the columns 16 and 16, the wedge when in place being capable of movement longitudinally of the carriage 15 and being situated above, and parallel to, the screwed spindleo.

Projecting from the carriage 15 are two brackets 21 through which passes a spindle 20. Two arms, 19 and 19, arranged in the form of an X and fitted with rollers 22 and 22, situated so as to be capable of being drawn into engagement with the edges of the wedge 17 by a spring 23, pivot around the spindle 20, in order to facilitate their contact with the edges of the wedge 1?, under the influence of the spring 23.

Pivoted at 38 on the arm 19 is an arm or catch 87 provided, near one end thereof with a notch 39, said notch being capable, when the arms 19 and 19' are forced apart by the wedge 17, of being forced into engagement with a pin 41 situated on the arm 19' by means of a spring 40 acting upon the upper edge of the catch 37, thus locking the arms in their extended position. Actuated by the bottom of the arms 19 and 19 respectively are a pair of pins 42 and 42 situated so as to engage the threads of the screwed spindle 5 when the rollers 22 and 22 are in engagement with the edges of the narrow part of the wedge 17, but to be held out of engage ment therewith when the rollers are forced outward and the notch 39 engages the pin 41.

Attached to a suitable part of the chassis 2 1 is an inclined plane 44, said inclined plane being adapted to raise the catch 37 and lift the notch 39 out of engagement with the pin 41 upon the said catch 37 coming in contact therewith.

Suitably attached to the chassis 2 1: so as to be readily accessible to the driver is a pedal as suit-ably connected to a pedal rod e7.

To prevent the carriage or slide exercising any twisting strain on the so "ewed spindle 5, and to facilitate the movement of the carriage along the chassis 24E, rollers 25 and 25 are attached to the carriage and roll along a slide formed by a wing of the chassis 2st and a guide 26.

The cross tie 13 carries a buffer 35, the purpose of which is to move the wedge 17 back into its normal position (as illustrated at Fig. 1) at the end of each operation.

Projecting from a suitable part of the carriag 15 is a shaft 27 on which is pivotally secured aroller 28, adapted to contact at the proper moment with the inclined plane 29 on the forked lever 9 and so throw the shaft 2 out of connection with the worm 6; Through its displacement under the action of the motor, the carriage 15 compresses the starting spring 30, which is mounted on the screwed spindle 5. To the carriage 15 there is fixed a single cable or its equivalent 31, which passes over a pulley 32, makes a turn around the free wheel or ratchet pulley or coiling box 33 mounted on the shaft 1, and then rolls up around the drum 34. The pulley or coiling box 33 turns with the shaft 1 when the latter rotates in the direction of the arrow X, but moves freely when the shaft rotates in the contrary direction.

In its normal state, when the engine is at rest the starting spring 30 is compressed, the roller 28 is in engagement with the inclined face 29 of the arm 9 thus holding the clutch member 7 out of en agement with clutch member 8, the end of the wedge 17 held at all times out of engagement with the pedal rod 17 by the spring 30, the rollers 22 and 22 are in contact with the narrow part of the wedge 17 and consequently the pins 42 and 42 are in engagement with the screwed spindle 5. When it is desired to start the motor, the pedal l6 is depressed as indicated by the arrow (Fig. 1) thus moving the pedal rod 17 and consequently the wedge 17 in a direction opposite to that indicated by the arrow. The inclined sides 36 and 36 of the wedge 17 move the rollers 22 and 22 out ward, thus extending the arms 19 and 19 and drawing the pins 12, e2 out of engagement with the screwed spindle 5, the spring 10 acting upon the catch 37 and forcing the notch 39 to engage the pin a1 and thus secure the arms in their extended position. In that position as the spindles 42 and 42 no longer engage the thread of the scr wed spindle 5, the spring 30 is free, and upon its release, it drives before it the carriage 15 which carries along the cable 31. The cable unwinds from the drum 3% and, passing over the free wheel coiling box 33, it causes same to make several revolutions, thus rotating the shaft 1 and starting the motor. As soon as the roller 28 has moved out of engagement with the inclined face 29 of the arm 9 the sprin 15 moves the clutch member 7 into engagement, thus connecting the shaft 2 with the worm 6. .Vhen the starting has been accomplished the wedge 17, will come up against the bufier o5 and will be moved thereby back to its original position on the carriage 15, the projection 43 on one extremity of the catch 37 will be lifted up by the upper portion of the inclined plane 14:, thus lifting the notch 39 out of engagement with the pin 41 and, under the action of the spring 23, the rollers 22 and 22 will again come into contact with the parallel sides on the narrow part of the wedge 17, while the pins 4-2 and 412 will reengage the screwed spindle 5. When the motor has been started it will rotate the screwed spindle 5 and move the carriage 15 therealong, thus compressing the starting spring and returning the carriage 15 to the position required for starting the motor. At that position the roller 28 on the carriage 15 as it passes over the inclined plane 29 of the forked lever 9 will put the clutch member 7 out of gear and the screw 5 will thus be brought to a standstill.

If desired, the intermediate shaft 2 may be coupled directly to the screwed spindle 5, by means of the worm 6 or by a bevel pinion, without employing the clutch 7 as an intermediate link, any other intermediary being used.
